(NEXSTAR) — Thanksgiving could not be any later this year but have no fear, it's right around the corner. And if you have a massive turkey taking up space in your freezer, it's not a moment too soon. Depending on the size of your turkey, however, your thawing time may be running out. While a turkey is in the freezer, it is "safe indefinitely" from bacteria, according to the U.S. Food Safety and Inspection Service. Yes, the freezer part is important — the turkey needs to be kept where the temperature is consistent. That means your back porch, car trunk, basement, cooler, or anywhere else that is not a freezer will likely not do the job. Why is Thanksgiving so late this year? When it comes time to thaw, it's important to keep your bird at a safe temperature, the FSIS emphasizes. There are three ways deemed safe for turkey thawing but we'll get a less-than-ideal method out of the way: leaving it on your counter for an extended period of time. "A package of frozen meat or poultry left thawing on the counter more than 2 hours is not at a safe temperature," the FSIS explains. Sure, parts of the turkey may still be frozen, but the outer layer will most likely have entered the "Danger Zone" — between 40 and 140 degrees Fahrenheit — where foodborne bacteria can multiply quickly. To safely thaw your Thanksgiving dinner, here's what the FSIS recommends. How to thaw a turkey in the refrigerator For refrigerator thawing, you should plan for roughly one whole day for every four to five pounds your bird weighs. So, if you're planning to enjoy your turkey on Thanksgiving Day, and it's more than 24 pounds, you need to start the thawing process the Friday before Thanksgiving. If your turkey is 20 pounds lighter than that, you can wait until Thanksgiving Eve. Should you quit your job before the holidays?

When you are cooking your turkey, whether or not it was able to thaw, have a food thermometer handy. Once it reads 165 degrees Fahrenheit in the innermost part of the thigh and wing, and the thickest part of the breast, it is ready.
